Fireworks display risk assessment: a UK guide

Fireworks displays are among the most tightly scrutinised community events, and the risk assessment is where scrutiny lands first. The core questions: who is firing, from where, with what falling where — and what happens if the wind changes.

First decision: professional or volunteer firing?

Consumer fireworks (categories F2 and F3) can legally be fired by adults, and many community displays run this way with trained volunteers. Category F4 fireworks are for professional display operators only. The honest trade-off:

• A professional operator brings their own risk assessment, insurance and crew, and takes the firing risk off your committee. You still own the event around the display — crowd, traffic, stewarding.
• A volunteer-fired display keeps costs down but puts the whole safety case on your paperwork: who is trained, how, and what the firing procedure is. Your insurer's view matters here — ask them before you commit.

The geometry: firing site, fallout zone, crowd line

Every display risk assessment is built on three areas:

• Firing site — where fireworks are set up and fired. Fenced or roped, no public access from set-up to clear-up, no smoking, fireworks stored in closed boxes until use.
• Fallout zone (dropping zone) — where debris lands, downwind of the firing site. It must be clear of people, cars, buildings and anything flammable. The safety distances for each firework come from the manufacturer's instructions — respect the largest one, and remember wind direction decides where this zone actually is on the night.
• Spectator area — behind a physical crowd line, stewarded, with the distances the fireworks' instructions require between crowd and firing site.

Draw all three on your site plan, then draw them again for the other wind direction. If the site can't accommodate the fallout zone in likely winds, the site is wrong.

The rest of the assessment

• Weather limits — a wind speed and direction combination at which you delay or cancel, decided in daylight by a named person.
• Bonfire — if there is one, it's a separate hazard: built the same day (check for wildlife and children's hiding places), no accelerants, a keeper with an extinguisher, and a distance from the crowd and the firing site.
• Darkness — most display injuries have nothing to do with fireworks: trips and crushes in the dark. Light the routes and the exits, not just the display.
• Emergency access — a clear route for a fire engine or ambulance, agreed and kept clear.
• Misfires and clear-up — a written procedure: wait times for misfired tubes, a dawn sweep of the fallout zone before the public returns (schools and dog walkers arrive early).
• Neighbours and animals — advertised timings, warning nearby stables and farms, and finishing at a neighbourly hour.

Permissions, insurance and who to tell

You'll need landowner permission and public liability insurance that specifically covers a fireworks display — many general policies exclude it. Tell your local fire and rescue service about the display and bonfire; some councils ask you to notify them too, and displays on council land go through the council's events process with an event management plan. If you're selling alcohol at the display, that's a licensable activity needing a Temporary Event Notice.

Buy fireworks only from a registered supplier, and note the storage rules: keeping fireworks before the display has its own legal limits — your supplier can advise on quantities and timing.

Common questions

How far must spectators be from the fireworks?

The distance comes from the fireworks themselves — each firework's instructions state a minimum spectator distance, and your crowd line must respect the largest distance in the show, plus the fallout zone downwind. There is no single national number; the manufacturer's instructions govern.

Do we need to tell anyone we're holding a display?

Tell the landowner, your insurer, and the local fire and rescue service; check whether your council asks for notification or a full event process. If the site is near an airfield, railway or major road, seek advice — your council's events team will know who to ask.

Can we still run the display if it's windy?

Only if the wind is within the limits you set in advance and the fallout zone still lands clear. Write the limit down before the night, and give one named person the authority to delay or cancel — a crowd on site makes that decision hard, which is why it's made on paper first.
